Description

Technical Field

[0001] This utility model relates to the field of iron oxide production equipment, and in particular to a screening and filtration device for iron oxide. Background Technology

[0002] In the production of iron oxide, screening and filtration are crucial steps to ensure the uniformity and purity of the product particle size. Highly efficient screening equipment directly impacts the quality and production efficiency of iron oxide. With the expanding applications of iron oxide in coatings, magnetic materials, and other fields, its production scale is continuously increasing. Traditional screening equipment, due to its low screening efficiency, significant material residue, and inconvenient cleaning, can no longer meet the demands of modern production for precise particle size control and continuous operation. Therefore, there is an urgent need to optimize the screening process and equipment structure through technological innovation.

[0003] Existing iron oxide screening and filtration devices have significant drawbacks: First, they suffer from low screening efficiency. Traditional devices often employ static screening or unidirectional vibration, resulting in uneven distribution of iron oxide particles on the screen surface. Fine particles easily clog the mesh, while coarse particles cannot fully contact the screen surface, leading to lengthy screening times and insufficient precision. Second, cleaning the inner frame is cumbersome. After screening, residual material accumulates in the corners of the inner frame, requiring manual disassembly of multiple parts for cleaning. This not only increases labor intensity but also increases the risk of device loosening due to frequent disassembly. Furthermore, the vibration structure of existing devices is prone to fatigue damage to the screen, shortening the equipment's lifespan. Moreover, the inability to flexibly adjust screening parameters according to different particle size requirements limits their application scenarios. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a screening and filtration device for iron oxide, which aims to solve the problems of low screening efficiency, cumbersome inner frame cleaning, and insufficient automation in existing iron oxide screening and filtration devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A screening and filtration device for iron oxide includes a rear plate. Rotating rods are rotatably connected to both the left and right ends of the front side of the rear plate. A sprocket is fixedly connected to the front side of the left rotating rod, and a gear is fixedly connected to the front end of the right rotating rod. The outer walls of the sprocket and the gear are connected by a toothed chain. Turntables are fixedly connected to the front sides of both the sprocket and the gear. Rotating frames are connected to the front sides of the turntables at both ends by connecting components. Limiting components are provided at both the left and right ends of the top side of the rotating frames.

[0007] Furthermore, the connecting component includes a connecting strip, a second rotating shaft is fixedly connected to the top side of the connecting strip, the rear side of the second rotating shaft is rotatably connected to the front side of the turntable, a first rotating shaft is fixedly connected to the bottom side of the connecting strip, and the bottom sides of the first rotating shafts at both ends are rotatably connected to the top sides of the rotating frames at both ends, respectively.

[0008] Furthermore, a motor is installed at the left end inside the rear plate, and the drive end of the motor is fixedly connected to the rear side of the rotating rod at the left end.

[0009] Furthermore, the limiting component includes a torsion spring, and both ends of the torsion spring are connected to telescopic rods. The opposite ends of the bottom sides of the telescopic rods are respectively rotatably connected to the front and rear ends of the top side of the rotating frame.

[0010] Furthermore, the rotating frame has a through groove inside, and an inner frame is provided inside the through groove. A filter screen is fixedly connected to the bottom end of the inner wall of the inner frame.

[0011] Furthermore, limiting grooves are provided on both the left and right sides of the through groove, and limiting blocks are fixedly connected to both the left and right sides of the inner frame, with the limiting blocks located inside the limiting grooves.

[0012] Furthermore, mounting frames are fixedly connected to both the left and right ends of the front side of the rear plate. The mounting frames are located on the bottom side of the rotating rod, and mounting grooves are provided on the adjacent sides of the mounting frames at both ends.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, iron oxide is placed in the inner frame, and the motor is started to drive the left end rotating rod to rotate the sprocket. The right end rotating rod and gear are rotated through the toothed chain, which in turn drives the two turntables to rotate. Because the two rotating shafts are installed at opposite ends of the turntables, the height of the two ends of the rotating frame alternates up and down during rotation, causing the iron oxide in the inner frame to shake, thereby improving the screening efficiency.

[0016] 2. In this utility model, after screening, the torsion spring is actuated to drive the telescopic rod to rotate and extend, releasing the limiting block and allowing the inner frame to be removed for cleaning. After cleaning, the inner frame is placed back into the through slot, the limiting block enters the limiting slot, the torsion spring is released to spring back, and the telescopic rod retracts to reset and fix the limiting block. This operation is convenient and facilitates subsequent use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a screening and filtration device for iron oxide, comprising a rear plate 1, with rotating rods 14 rotatably connected to both the left and right ends of the front side of the rear plate 1. A sprocket 12 is fixedly connected to the front side of the left rotating rod 14, and a gear 13 is fixedly connected to the front end of the right rotating rod 14. The outer walls of the sprocket 12 and the gear 13 are connected by a toothed chain 11. A turntable 10 is fixedly connected to the front side of both the sprocket 12 and the gear 13. A rotating frame 6 is connected to the front side of both turntables 10 by a connecting strip 8. Torsion springs 20 are provided at both the left and right ends of the top side of the rotating frame 6. A second rotating shaft 9 is fixedly connected to the top side of the connecting strip 8, and the rear side of the second rotating shaft 9 is rotatably connected to the front side of the turntable 10. A first rotating shaft 7 is fixedly connected to the bottom side of the connecting strip 8, and the bottom sides of the first rotating shaft 7 at both ends are rotatably connected to the top sides of the rotating frames 6 at both ends. A motor 15 is installed at the left end inside the rear plate 1, and the drive end of the motor 15 is fixedly connected to the rear side of the left rotating rod 14.

[0025] Specifically, when using this iron oxide screening and filtration device, the iron oxide to be screened is first placed into the inner frame 16. Then, the motor 15 is started, which drives the left-end rotating rod 14 to rotate. The rotating rod drives the sprocket 12 to rotate. Since the sprocket 12 and the gear 13 are connected by a toothed chain 11, the rotation of the sprocket will drive the right-end rotating rod 14 and the gear 13 to rotate, thereby driving the two turntables 10 to rotate. The two rotating shafts 9 are installed at the opposite ends of the two turntables 10. Therefore, when the turntables rotate, the height of the left and right ends of the rotating frame 6 will move up and down, and will not be at the top or bottom at the same time. This causes the iron oxide in the inner frame 16 to shake, improving the screening efficiency.

[0026] Reference Figure 1 , Figure 3 and Figure 4 The torsion spring 20 is connected to telescopic rods 18 at both ends. The opposite ends of the bottom sides of the telescopic rods 18 are rotatably connected to the front and rear ends of the top side of the rotating frame 6. The rotating frame 6 has a through groove 21 inside. The through groove 21 has an inner frame 16 inside. The bottom end of the inner wall of the inner frame 16 is fixedly connected to a filter screen 17. Limiting grooves 22 are opened on both the left and right sides of the through groove 21. Limiting blocks 19 are fixedly connected on both the left and right sides of the inner frame 16. The limiting blocks 19 are located inside the limiting grooves 22. The left and right ends of the front side of the rear plate 1 are fixedly connected to mounting frames 2. The mounting frames 2 are located on the bottom side of the rotating rod 14. The adjacent side of the mounting frames 2 at both ends has a mounting groove. The mounting groove is slidably connected to the mounting strip 3. The adjacent side of the mounting strip 3 at both ends is fixedly connected to a collection frame 4. The front side of the collection frame 4 is fixedly connected to a pull handle 5. The collection frame 4 is located on the bottom side of the rotating frame 6.

[0027] Specifically, after screening, the torsion spring 20 is activated, causing the two telescopic rods 18 to rotate and extend, releasing the limit block 19. Then, the inner frame 16 and any remaining iron oxide are removed. After cleaning the inner frame, it is reinserted into the through groove 21, allowing the limit block 19 to enter the limit groove 22. The torsion spring 20 is released, and it automatically rebounds, causing the two telescopic rods 18 to retract and reset, re-fixing the limit block 19. Finally, pulling the handle 5 removes the collection frame 4 and the screened iron oxide inside.

[0028] Working principle: In use, the iron oxide to be screened is first placed inside the inner frame 16. Then, the motor 15 is started to drive the left-end rotating rod 14 to rotate the sprocket 12. Since the sprocket 12 is connected to the gear 13 through the toothed chain 11, the rotation of the sprocket 12 will simultaneously drive the right-end rotating rod 14 and the gear 13 to rotate, thereby driving the two turntables 10 to rotate. The two rotating shafts 9 are installed at the opposite ends of the two turntables 10. As the two turntables 10 rotate, the height of the left and right ends of the rotating frame 6 will move up and down, and will not be at the top or bottom at the same time. This causes the iron oxide inside the inner frame 16 to shake. The screening efficiency is improved. After screening, the two telescopic rods 18 can be rotated and extended by turning the torsion spring 20, thereby releasing the limit block 19. Then, the inner frame 16 and the iron oxide remaining inside the inner frame 16 are taken out. After cleaning the inside of the inner frame 16, the inner frame 16 is put back into the through groove 21 and the limit block 19 is put into the limit groove 22. Then, the torsion spring 20 is released, and the torsion spring 20 automatically rebounds, thereby driving the two telescopic rods 18 to retract and reset, and the limit block 19 is fixed again. After screening is completed, the collection frame 4 and the screened iron oxide inside the collection frame 4 can be taken out by pulling the handle 5.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
